superLU occasionally iterates on a matrix that has obviously become singular. fault_check can be put into the system to supplement this check, but there may be options inside superLU to fix it.

There do not appear to be any superLU flags to make it more
obust. Deferring this to 3.0 so as more examples pop up, we can handle them.

An approach to this may be to look for #INDs and other nasty results during the convergence check and variable update, failing out before superLU \converges\ to invalid answers.,
